Question 300
A security operations team receives this change request: A security analyst needs a recurring review of the same high-risk source subnet, but rebuilds an intricate device and action query every shift with inconsistent terms. Which ongoing safeguard best addresses the original risk?
Explanation
Correct Answer
Assign ownership and review cycles to shared investigation custom views. This long-term control addresses the recurring risk. The technical reason is: Custom views preserve analyst search context and can be private or shared, reducing differences between repeated searches. A later acceptance test still needs to confirm: A second authorized reviewer opens the saved view and sees the intended filtered records.
Incorrect Answers
This safeguard, “Document case-sensitive investigation requirements for application identities”, reduces a different source-defined risk: An endpoint's login records use both `Admin` and `admin`, but the team wants to distinguish their literal case for an application-specific account audit. That risk depends on: Log View searching is usually case insensitive; toggling sensitivity changes whether case variants are treated as matches. The recurring problem here is a security analyst needs a recurring review of the same high-risk source subnet, but rebuilds an intricate device and action query every shift with inconsistent terms. The originally selected control “Assign ownership and review cycles to shared investigation custom views” is more specific because custom views preserve analyst search context and can be private or shared, reducing differences between repeated searches.
This safeguard, “Pair negative search findings with log-source availability checks”, reduces a different source-defined risk: A hunt finds no malicious traffic during a three-hour window, but FortiAnalyzer Log Receive Monitor shows a branch stopped sending logs for two hours. That risk depends on: No query results cannot establish no threat activity when data ingestion was incomplete. The recurring problem here is a security analyst needs a recurring review of the same high-risk source subnet, but rebuilds an intricate device and action query every shift with inconsistent terms. The originally selected control “Assign ownership and review cycles to shared investigation custom views” is more specific because custom views preserve analyst search context and can be private or shared, reducing differences between repeated searches.
This safeguard, “Prefer reversible search filters over evidence deletion during triage”, reduces a different source-defined risk: An analyst wants to exclude routine security scanner traffic from a hunt but deletes those records from the displayed sample export. That risk depends on: A negative Log View predicate hides matching records from a view without destroying stored evidence. The recurring problem here is a security analyst needs a recurring review of the same high-risk source subnet, but rebuilds an intricate device and action query every shift with inconsistent terms. The originally selected control “Assign ownership and review cycles to shared investigation custom views” is more specific because custom views preserve analyst search context and can be private or shared, reducing differences between repeated searches.
